I have a similar example. It’s a very short street only about a block long named Brittany Trace. The street sign on one end of the road correctly reads “BRITTANY TR”, but the sign on the other end of the street reads “BRITTNAY TR”. I’ve been tempted to take down the incorrect one… I noticed the signpost was completely missing last time I was there, so I can only conclude that someone ran into it and knocked it down. 🙂
